How Does Cardiac Arrest Occur?
A sudden cardiac arrest is caused due to obstruction in the vessels carrying blood to the heart. This gives rise to pain, numbness in the chest, and shortness of breath. In the event of a cardiac arrest, the patient should be rushed to the hospital at the earliest possible to avoid fatal consequences.
But some types of arrhythmia can be serious and lead to a sudden stop in heart function (sudden cardiac arrest). The most common cause of cardiac arrest is an arrhythmia called ventricular fibrillation — when rapid, erratic electrical impulses cause your ventricles to quiver uselessly instead of pumping bloodshed is a disease in which a waxy substance called plaque (plak) builds up in the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle.
Plaque narrows the arteries and reduces blood flow to your heart muscle. Eventually, an area of plaque can rupture (break open). This may cause a blood clot to form on the plaque’s surface.A blood clot can partly or fully block the flow of oxygen-rich blood to the portion of the heart muscle fed by the artery. This causes a heart attack.
During a heart attack, some heart muscle cells die and are replaced with scar tissue. The scar tissue damages the heart’s electrical system. As a result, electrical signals may spread abnormally throughout the heart. These changes to the heart increase the risk of dangerous arrhythmias and SCA.CHD seems to cause most cases of SCA in adults. Many of these adults, however, have no signs or symptoms of CHD before having SCA.
Cardiovascular diseases are the leading causes of death globally with an estimated 17.9 million people succumbing to the same in the year 2016. Following are some of the primary causes of cardiac arrests:
● Smoking – Regular smoking reportedly causes cardiac arrests and cardiovascular diseases.
● High Blood Pressure and Cholesterol – Diet rich in unsaturated fat gives rise to high cholesterol that clogs blood vessels resulting in cardiac arrest.
● Obesity and Diabetes – High body mass index and uncontrolled diabetes are one of the prominent triggers of cardiovascular diseases.
● Age, Gender, and Genetics – Cardiac arrests most likely arise with old age. Moreover, and a family history of this condition makes one more vulnerable to its incidence.
Depending on the severity of the cardiac arrest, the patient may either by treated with medicines & lifestyle changes or be advised for surgery.
Cardiac surgeries being a complex medical procedure, recovering from the same may often take longer. It’s only with customized rehabilitation that one’s smooth transition into regular life can be ensured.
